1. virtio devics/drivers match and probe/remote mechanism;
2. virtio mmio transport layer based on OpenAmp (Compatible with both
virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
(IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only
support mmio transport layer, and the new framwork support
more transport layer and this commit has implemented all the
old virtio drivers;
8. Refresh the the qemu-arm64 and qemu-riscv virtio related
configs, and update its README.txt;
New virtio-net driver has better performance
Compared with previous virtio-mmio-net:

|
|
* drivers_initialize will be called once during OS initialization after
|
|
* the basic OS services have been initialized.
|
|
*
|
|
* drivers_initialize is called after the OS initialized but before the
|
|
* user initialization logic has been started and before the libraries
|
|
* have been initialized. OS services and driver services are available.
